Title: Turbo molecular pump
Inventor: MIYAZAKI MASAYUKI
IPC: F04D19/04
Filed: 1986-05-30
Abstract: PURPOSE:To prevent degradation of the rotary performance by supporting a rotary member having a rotor blade by means of a lower bearing in the central protion of a mortor. CONSTITUTION: A rotor 4 of a motor is shrinkage fitted over an outer cylindrical section of a rotary shaft 15. The lower end of an inside post section 17 of the rotary shaft 15 is supported by a spherical spiral groove bearing 12 and it is positioned in the central portion of a rotor 4 of the motor.

Title: High speed jet pump for gas-liquid two-phase flow
Inventor: OKAMOTO YOSHIHARU
IPC: F04F5/10
Filed: 1982-07-19
Abstract: PURPOSE:To enable suction and flow of solid and particle material by arranging nozzles on a pressure water feed pipe while conducting/securing an outer pressure air lead pipe to the side wall of thin section at the tip of nozzles then feeding the outer pressure air on the high speed water flow through said thin section. CONSTITUTION:Water is pressurized by a pressure water system and fed into a pressure water feed pipe 1 to produce high speed flow through a thin tube 3 at the nozzle section 2, while the outer air is sucked at the end of an outer pressure air lead pipe 4 provided in the way of the thin tube 3 to produce mixture of gas and liquid to jet high speed water flow from the tip of the thin tube 3 into a delivery tube 6. Then the static water in the delivery tube 6 is induction accelerated to enable suction/feed of even solid material, particles, wood chip, vinyl, etc. through the tip of the suction tube 5. Consequently the structure can be simplified because it requires no conventional pressure air. When placing a nozzle tip section abrasion reducing tube 7 between the tip of the thin tube 3 and the delivery tube 6, abrasion at the tip section of the thin tube 3 can be reduced.

Inventor: SAKAI NAOTO
IPC: B65G53/18
Filed: 1977-10-22
Abstract: PURPOSE: To heighten the compression efficiency of compressor and the capacity of discharge, by opening one end of an ejector pipe opened into the upper part of tank and connecting the other end of the ejector pipe to a halfway part of a discharge pipe extending between a tank and a storage tank.  
     CONSTITUTION: Compressed air is supplied from the compressor 5 into an air chamber 3 at the bottom of the tank 1 and is introduced into the tank 1 through a canvas 2. The air is mixed with granular matter in the tank to fluidize the matter. A part of the air is filtered by a filter 13 and flows into an air chamber 14. When the granular matter becomes hard to discharge because of the increase in the flow resistance of curved part of a throw-in pipe 9 and the pressure in the tank reaches a certain level, an air valve 16 is opened to conduct a part of the air from the tank to the discharge pipe 6 through the ejector pipe 15. Thereby, the granular matter in the discharge pipe 6 can be effectively discharged to the storage tank.

Title: Photo branching unit
Inventor: TANAKA YUUJI
IPC: H04B10/272
Filed: 1982-07-22
Abstract: PURPOSE:To eliminate the optical loss at a photo branching point of a photo branching unit by composing the unit of a logic circuit so as to supply electric signals produced from 3-direction photoelectric converters to all 3-direction electro-optical converters. CONSTITUTION:When information is fed to an optical fiber 11, the information is converted by a photoelectric converter to an electric signal, and supplied through an OR circuit 23 to electro-optical converters 18, 20, 22. The information is again converted by the converters 18, 20, 22 into optical information, and fed to optical fiber 12, 14, 16. In other words, the optical information from the optical fiber 11 is branched in two different directions, and simultaneously returned to an information oscillation source. When the optical information is supplied through fibers 13, 15, the information is similarly branched. According to this light branch passage, no optical loss exists different from the photo branch using a prism or the like. Accordingly, an optical communication can be reliably performed to the terminal even if many photo branch passages are connected in series. Further, the occurrence of collision with other optical information can be readily detected.

Title: Bar code reader
Inventor: SATO KOZO
IPC: G06K7/10
Filed: 1987-05-26
Abstract: PURPOSE:To easily set a parameter and at the same time to improve the degree of designing freedom by constituting a parameter memory means a RAM and storing the read parameter information in the RAM after scanning a bar code produced for setting the parameter. CONSTITUTION:A bar code 9 produced for setting a parameter is scanned before the bar code is scanned and read. Thus parameter information on a kind-based parameter, a transmission parameter, etc., are read and stored in a RAM 4. When a reading action of the code 9 is started, the read bar code information is decoded based on the type-based parameter stored in the RAM 4. While the decoded data is transmitted to a host computer connected to the outside based on the transmission parameter. Thus a parameter setting operation is facilitated and furthermore, the designing freedom degree is also improved.

Abstract: PURPOSE:To prevent the contamination at the end face of a disk by an adhesive agent coated to an annular shape and the degradation in function as a spacer by embedding a hollow pipe into at least one point of the adhesive agent so as to cross the ring. CONSTITUTION:The hollow pipe 5 is embedded into at least one point of the adhesive agent 3 coated to the annular shape so as to cross the ring and thereafter two substrates 1a, 1b are superposed at the time of producing the optical information recording disk medium having hollow structure by coating the adhesive agent 3 to at least one of the substrates 1a, 1b along the respective inside and outside peripheral edges thereof to the annular shape and superposing and sticking the two substrates.
